How much of a 5.0 m sucrose solution should you use to make 85.0 ml of a 0.040 m solution?

The volume of concentrated sucrose solution required is 0.68 mL

Explanation:

To calculate the volume of concentrated solution, we use the equation:

where,

are the molarity and volume of the concentrated sucrose solution

are the molarity and volume of diluted sucrose solution

We are given:

Putting values in above equation, we get:

Hence, the volume of concentrated sucrose solution required is 0.68 mL

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
